In the process of using Windows, we may have encountered such situations: the system restarts, shuts down or becomes blue screen, black screen without any warning or notice. Then you can no longer log on to the system, or get into an endless loop of blue/black screen + reboot. This case, you may first think that this is probably caused by hardware failures. However, that is almost always caused by conflicts between hardware drivers or errors of system kernel modules. The former is usually shown as a blue screen (+ restart), while the latter is usually shown as an automatic restart by default.

As Windows' fatal, non-interferential system error - this is often referred to be system crash, Blue Screen (AKA: Blue Screen of Death, BSoD for short) - it's just as classic and famous as Windows OS itself!
